Britain’s Got Talent bosses have reportedly stepped up security for the show’s stars over fears the show could be targeted in an acid attack.

The BGT stars have been pictured surrounded by security while travelling to and from auditions which are being held at the London Palladium.

According to the Daily Star, extra security has been drafted in to protect BGT judges Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams, as well as presenters Ant McPartlin and Declan Donnelly.

The publication reported that bosses aren’t taking any chances this year, following a spree of acid attacks across the capital.

People attended the auditions have also noticed the heightened security measures, with one person taking to Twitter to complain about security guards confiscating any open bottles of liquids.

“London Palladium are stopping people taking opened bottles of water/drink in… Then they’re selling 500ml bottles of water to audience members for £2.50. Presumably due to risk of acid attacks? They didn’t do this a year ago. How sad they’ve decided to profit from the situation!” they tweeted.

Meanwhile, a spokesperson for BGT told the Daily Star, ““We take the safety around the show very seriously. We continually review security procedures to meet our needs.”
